Extended Data Fig. 2: The structural transformations of ZnGGH and the experimental workflow for triggered guest adsorption.
From: Chemical control of structure and guest uptake by a conformationally mobile porous material
a, Eight distinct crystal structures are produced by exchanging the molecules that occupy the pores of as-made ZnGGH-1⋅(DMF-H2O). b, Experimental procedure for the adsorption of dioxane by ZnGGH-2 with (left) and without (right) triggering by DMF. Adding DMF during the dioxane-adsorption experiment produces a structural transformation and allows dioxane to access the ZnGGH framework. In the absence of DMF, dioxane does not access the pores of ZnGGH-2. PXRD and 1H-NMR data are shown in Fig. 2. The small amount of dioxane measured in the non-triggered adsorption is assigned to surface species that are not removed during the required work-up procedure.
